Pro-Volt ,dry cell high amp battery.

I found a high power replacement
battery for the Miata...(That Fits) It`s a Pro-Volt that you can get at Summit
Racing.It`s specs are 1100cca/50ah,33 lbs,brass terminals,-40 to 140 temp rated,deep
cycle rated,2 year full replacement.Its measurements are 7.79"long,6.54"wide,6.73"high.The
only mod I had to do was to remove one of the end brackets on the top clamp
but it fits perfect.PT# PVT-890000 and yes it uses the same dry cell tech as
the stock battery.In fact you don`t have to vent it.

I was getting tired of the weak stock
Miata battery and it just about dying everytime I left my car parked for more
than 3 days.After the install the car turns over like it is supposed to not
like a hot high compression big block.I am very satisfied with this battery
and the power it has.I can leave my stereo on for more than a half an hour without
worrying my car wont start.
